I'm glad they're reporting it as the energy storage capacity and not the power output capacity. Too many news sites like to report the power output capacity in stories like these, which is horribly misleading, and then often they also frame it as though this is equivalent to adding actual power generation to the grid, which is even more misleading.

SELV usually is defined to have both a voltage limit and a volt-amp (ie: power) limit. Generally defined somewhere around 60V peak to peak and 250V*A.

48V is under the SELV voltage limit, even with some margins.

But historically, some countries have had lower limits. I recall Japan being one of them for a while. I'm not confident that SELV is a harmonized standard worldwide, or at least it wasn't until recently, if it is now.

The browsers could kick ALL their keys out and break all of eMudhra's customers websites. Those customers could sue.

Many HSMs do not force you to use unique labels for keys. So it's somewhat understandable if a human mixed up some keys during a non-standard or deviated process. This doesn't explain how so many different keys were "generated" so poorly or why no one cared about mismatched signatures.

And the discussion mentioning wrap/unwrap testing kind of feeds directly into the fear that either:

1. These weak keys were created outside the HSM and then imported.

2. These weak keys were meant to be the wrap keys somehow. Like, if they hadn't paid for some of the wrap/unwrap features on one of their HSMs and so were using easy-for-humans keys to handle the wrap/unwrap operations so they could more easily move keys between HSMs.

Good leadership requires brains. Average leadership is attainable without brains.

Curious how realistic the skills learned in such a program are still applicable in 1-2 years. This industry is moving very fast, it feels like the self motivated, self starter, self learner has been thriving. Probably a good thing to have such a program, but I have doubts.

Before we had LLMs, we had product managers, project managers, scrum leaders, etc as roles on software engineering teams. I think as LLM-enabled development progresses we'll start to see these roles and the crossover to engineering continue to meld.

It's not like engineers didn't know that project management, voice of the customer, and organizing tasks as an intermediary between engineering and management was a thing that could/should/needed to be done. It was just a delegation of tasks before because there was more work than one person could do. Now, all of these roles can be partly offloaded to LLMs, but still having a human in the loop to guide engineering and interface to the business/customer will still be valuable.

Knowing what to build overall, what to build next, what's coming later, and how the product relates to the business goals is still very much a human endeavor.

Feels more like perforce, but effectively, yes.

A few ideas on why reducing profit by investing into the company might not be their best choice without the new investment round:

Hiring people is hard, takes time, and timing of big sales closing causing income may not line up well enough with the hiring process to offset that income fully.

Their machines are sold for high prices. It’s not small and not cheap. If a buyer pays in a lump sum that can be a big income and Oxide may not be able to time that ideally for tax purposes.

Buying electronics components is funny. Want to buy 1000 units? Price X. Want to buy 100,000 units, price is X/25. But till you can place an order for every component at the 100,000 quantity, you can’t get those price breaks so your cost to manufacture machines is much higher. $400M may let them buy at those bigger quantities and get those price breaks and it may not have been worthwhile to buy inventory at the lower quantity pricing if the investment round was looking to close real soon now. Cash flow is king, and hard, for hardware companies.

Unless you plan to physically assault it with weapons, it’s extremely unlikely to catch fire.

Berget's "Cached input tokens are billed at the same rate as regular input tokens" pricing model is kind of painful for lots of coding use-cases, especially when competitors are offering significant discounts for cached input tokens.

There has been massive innovation and development in apples in the past 20 years. Every apple farm with a clue is growing trees for the past decade that look nothing like the trees of old. They’re growing varieties that didn’t exist 20 years ago. If you’re still seeing Red Delicious anywhere, it’s on the buyers at your local markets that missed the boat.

Just read the terms of service and read this blog post and I think your concern will be addressed.
